The measurement of thin oil films under dynamic loading conditions using light and x-ray techniques

Abstract

A study was made of the behavior of thin oil films under dynamic loading conditions using light and x-ray techniques. This was done by passing light and x-ray beams between two cylindrical disks which suddenly squeezed oil films between them. The light technique presents a time variation of oil film thickness under sudden load conditions with good results. The x-ray technique attempted to measure counts from the x-ray beam during the very short time interval of minimum film thickness. (Author)
